A series of coordinated attacks on hotels and churches devastated Sri Lanka on Easter Sunday leaving at least 250 people dead and hundreds more injured. The Health Ministry revised the death toll from 359 casualties on April 25, blaming it on a calculation error, reported BBC.

A total of nine bombers have been identified by the authorities for carrying out the attacks.

According to reports, two brothers Ilham Ahmed Ibrahim, 31, and Imsath (or Inshaf) Ahmed Ibrahim, 33, have been identified as the suspected bombers during the attacks. Inshaf Ibrahim, a copper factory owner, is accused of being the mastermind behind the bomb plot.

The nation’s Deputy Defense Minister Ruwan Wijewardene said that when police went to raid the brothers’ home in Dematagoda shortly after the bombings, the pregnant wife of one of the brothers, who was identified as Fatima Ibrahim, detonated a suicide vest she was wearing killing herself, her unborn child, two other young children, and three police officers, reported ABC.
